v0.6.10

Fixed:

• Detect prefix-wide path-to-trailing-slash normalization before it can fill the recursion directory cap.
• Confirm redirect catchalls with two bounded concurrent random siblings.
• Preserve real directory redirects whose response fingerprint differs from the learned catchall.

Changed:

• Share one single-flight redirect check per parent with no new CLI flags.
• Update README, changelog, package metadata, and lockfile for v0.6.10.

Verified:

• cargo test --locked (207 passed)
• cargo build --release --locked
• A controlled concurrent fixture suppressed generic redirect roots and still found the distinct nested real child.
